The Automotive composites Alliance is pushing thermoset plastic composites for a wide variety of applications in hybrid cars, including modules that contain the battery pack, electronic controller and wiring harness. In the US the modules are typically made of several metal stampings which are assembled. Use of composites could reduce the module to two pieces with major savings in weight as well as tooling investment. “Unlike metal, composites don’t conduct electricity, therefore providing an extra safety advantage,” says the Alliance report. “They also won’t corrode and allow integrated airflow cooling in the module’s tunnel, all adding to longer battery life.”
A composite based on a high-performance PEEK-like resin we told you about two years ago when it was still in R&D has now been licensed by the US Naval Research Laboratory (NRL) for commercial manufacturing.
Microsoft, HP, Dassault, and other industry heavyweights in 3D printing have launched a new 3DP file format, 3MF. The consortium says the spec will more fully describe a 3D model and will be interoperable with multiple applications, platforms, services, and printers.
NASA's been working on several different ongoing projects for 3D-printed rocket engine components in metals and now it's reached another first in aerospace 3D printing: a full-scale, 3D-printed rocket engine component made of copper.
